Title: Interoffice broadband communication system using twisted pair telephone wires
Inventor: ROGERS STEVEN
IPC: H04M11/06
Filed: 1998-01-21
Granted: 1999-08-11
Abstract: A system including a broadband switch includes a controller which coordinates video call set-up and a switch for connecting various phone lines together through diplexers. The system permits video telephone conferencing and other video related applications to be performed over ordinary telephone wires. Two diplexer/modems are typically provided for each user; one at the user's telephone jack and another at the central PBX location for that user's telephone line. The PBX connections can usually be made in a central wiring closet. A video server can also be provided which retrieves video images from disk to provide on demand to users. The existing PBX handles the switching or normal telephone audio signals, and a broadband data switch handles the switching of broadband signals over the same telephone wires that the PBX uses. The broadband switch essentially "piggybacks" off the PBX system and avoids interference with telephone signals through the use of diplexers.

Title: Capacitive pressure sensing method and apparatus
Inventor: HAASE WAYNE C
IPC: G01L9/12
Filed: 1998-03-05
Granted: 2001-05-16
Abstract: A capacitive pressure sensor includes a chamber coupled to a region whose pressure is to be determined. The sensor includes a conductive flexible diaphragm and a pair of electrodes, each defining a capacitance with the diaphragm. Variations in pressure in the chamber cause deflection of the diaphragm which in turn causes variation in the capacitances. A processing circuit applies an excitation signal to the capacitances and couples the capacitances to inductive elements. A current through the inductive elements is detected to determine the difference in the sensor capacitances and therefore, the deflection of the diaphragm and the pressure in the chamber.

Abstract: A method and apparatus for wireless transmission of data through a communications channel between at least two local data sensors (for example automotive diagnostic data sensors or NVH sensors), which may include a primary data-processing function, and data- processing function (for example a PC) to receive data therefrom. The system provides for asymmetrical division of the communications channel on a frequency or time-division or packet-switching basis so that the corresponding asymmetrical data transmission requirement of the local data sensors are matched to the capacity of their respective sub-channels whereby a single channel is capable of transmitting all the required data. A particularly practical application is to noise vibration harshness analysis of wireless- transmitted data from three-dimensionally spaced NVH sensors enabling special pinpointing of vibration sources in automotive warranty analysis studies.

Title: Method for reforming polymer surface for improved wettability
Inventor: LEE SANG-YOUNG
IPC: H01M50/494
Filed: 1999-05-17
Granted: 2003-08-21
Abstract: The present invention relates to a method for reforming the surface of polymer, especially to a method for providing hydrophilicity or increasing hydrophobicity by reforming the surface of polymer or polymer membrane. The present invention is a method for reforming the surface of polymer membrane by irradiating it with energized ionic particles under the vacuum condition. The method including the steps of: (a) manufacturing polymer membrane, including a surface activated, by inserting polymer membrane into a vacuum chamber, and by irradiating energized ionic particles on the surface of polymer membrane with an ion beam under a high vacuum; and (b) manufacturing polymer membrane treated with a reactive gas on the surface of membrane, including the activated surface of step (a), by infusing the reactive gas into a vacuum chamber after energized ionic particles of step (a) have been irradiated. The methods in the present invention can achieve their objects to reform the surface to provide hydrophilicity of hydrophobicity without deteriorating mechanical properties of the polymer membrane. Additionally, it can also contribute to an improved working environment and readily accommodate mass production techniques because the surface reforming of polymer membrane is a relatively simple technique that does not employ solvents.
